WELL-BORING APPARATUS.

To all whom it may concern:

Be it known that I, ANDREW K. WALLEN, Sr., a citizen of the UnitedStates, residing at Jackson, in the county of Hinds and State ofMississippi, have invented certain new and useful Improvements inWell-Boring Apparatus, of which the following is a specification.

My present invention pertains to improvements in well-boring apparatus,the construc tion and advantages of which will be herein after setforth, reference being had to the anneXed drawings, wherein Figure 1 isa top plan view of the apparatus, portions thereof being broken away tomore clearly illustrate the construction; Fig. 2, a side elevationthereof; Fig. 3, a sectional view on the line 2 2 of Figs. 1 and 2, andFig. 4 a detail view of one of the yielding clamping plugs or blocks.

The object of my invention is to provide a simple and eflicientmechanism for boring wells, and more particularly for lowering the pipeor easing into the same.

Referring to the drawings, A denotes the framework, upon which issecurely bolted the supporting member B, having a raceway or track inthe upper face thereof. Said member B is also provided with adownwardlyextending skirt G, into which fits a collar D, formed as apart of a plate E. Said plate is provided with a ball-racewaycomplemental to that of the member B, balls being interposed betweenthese two parts to permit rotation of the plate E and the parts attachedthereto.

F denotes the clamp-supporting bed or table, provided with a rim or tireG to properly strengthen the same.

A worm-gear H and a riser block or member I are interposed between theplate E and the clamp-supporting table F, these members being allsecurely fastened together by bolts J, which pass therethrough, as shownmost I clearly in Fig. 3.

A shaft K is mounted in suitable boxes or bearings L, adjustably securedupon the framework A or blocks mounted thereon. A worm M is secured tosaid shaft and meshes with the gear H, as clearly indicated in Figs. 1and 2. Motion is imparted to shaft K through a pulley N or in any othersuitable manner. The construction shown is preferable, however, as saidshaft may be driven by a belt, as shown in Fig. 2, this arrange-Specification of Letters Patent.

ment leaving the space about the apparatus practically unobstructedapoint of material advantage in machines of this character.

Mounted upon the member F is a clamp which comprises two heavy timbersor blocks O 0, each formed with a semicircular recess in its faceadjacent the corresponding member. The walls of these recesses areprovided with a series of seats or sockets, into which are forced blocksor plugs P of any suitable yielding materialas, for instance, rubber. Aswill be seen upon reference to Fig. 1, the members 0 do not abut,although they may be forced one toward the other by bolts Q, which passhorizontally through them, each of said bolts being provided at one endwith an enlarged eye B, into which a lever may be inserted for thepurpose of turning the bolt and causing it to screw through its nut, andconsequently draw the clamping members 0 together.

Hooks S are pivotally secured to the bed F, the free end of each hookpassing into an eye T or the like, secured to the adjacent member O ofthe clamp.

With the construction above set forth it will be seen that as motion isimparted to the table or supporting-bed the clamp must of necessity movetherewith.

A well-boring machine constructed in accordance with the foregoingdescription has been found to give eminent satisfaction, the use ofworm-gear being advantageous over the ordinary bevelgearing or frictiondrive and likewise more powerful in its action. The clamp also forms asafe device for use in lowering the pipe and auger when boring.

Having thus described my invention, what I claim is 1. In a well-boringmachine, the combination of a rotatable table; a clamp comprising twoblocks or timbers O, 0, each having a semicircular recess formed in theface adj acent to the corresponding member; yielding plugs mounted inthe blocks in line with said recesses bolts Q extending through saidblocks, one end of each bolt being provided with an enlarged eye R andmeans for securing said members 0 to the table.

2. In a well-boring machine, the combination of a rotatable table; aclamp comprising two blocks or timbers O, 0, each having a semicircularrecess formed in the face adjacent to the corresponding member; yieldingplugs mounted in the blocks in line with said In testimony whereof Ihave signed my recesses; bolts Q extending through said name to thisspecification in the presence of blocks, one end of each bolt beingprovided two subscribing witnesses.

with an enlarged eye R hooks pivotally secured to the table; and meansfor securing connection between said hooks and the blocks or timbers.
